I need to call the method getBitcoins() every second.
Tried: I tried just taking it out the methods and putting it under the line
import Pickaxe from '../assets/pickaxe.png'and then using setInterval to call it every second, but then I can't access the data variable btcPrice inside getBitcoins().
So I need a way to call the getBitcoins() from the methods functions every second, just as it is in the code below.
<template>
<div id="wrapper">
<div class="top"></div>
<!-- Center -->
<div class="center">
<img :src="Pickaxe" class="Pickaxe">
<span class="my-btc">{{ mybtc.toFixed(8) }}</span>
<span id="btc">1 BTC = {{ btcPrice }}</span>
<button class="Mine">Mine</button>
<span class="hashes">{{btcMin}} btc/min</span>
<button class="Upgrade">UPGRADE</button>
<span class="upgradePrice">{{ upgradePrice }}btc</span>
</div>
</div>
</template>
<script>
import bitcoin from '../assets/bitcoin.svg'
import Pickaxe from '../assets/pickaxe.png'
export default {
name: 'landing-page',
data() {
return {
bitcoin,
Pickaxe,
mybtc: 1,
btcPrice: null,
btcMin: 0,
upgradePrice: 0
}
},
methods: {
getBitcoins() {
var currentPrice = new XMLHttpRequest();
currentPrice.open('GET', 'https://api.gdax.com/products/BTC-USD/book', true);
currentPrice.onreadystatechange = function(){
if(currentPrice.readyState == 4){
let ticker = JSON.parse(currentPrice.responseText);
let price = ticker.bids[0][0];
document.getElementById('btc').innerHTML = "1 BTC = " + price + "$";
};
};
currentPrice.send();
}
}
}
</script>
